a citifnl Improvements in lhonog'raphs, of which the followingis a description.

residing at, Orange,

'i as shown at 6, to receive a spherical roller and a stud or center 8 formed on the pin 9, which is secured to the body 1. ljpou the shaft '2 is rotatably mounted a hollow shaft 10, formed with a feed screw My invention relates to phonographe and has for its object the provision of interchangeable meansy for feeding the traveling i carriage upon which mounted at either of two rates of speed, one of which may be suitable for operating upon a record of one hundred threads per ineh,kand the other for operating upon a record having` 200 thread` per inch. The particular means employed by me comprises a hollow rotary feed `screw mounted concentricallyv with respectto an inner shaft,

the sound box '1s` and capable of being locked to said shaft so holes or openings 1S, formed 1n the spur as to rotate therewith, or of being unlocked therefrom and driven through interposed i gearing so as to rotate aty a dlllereut rate of speed.

lu order that my' invention may be more fully understood,referenceis hereby made to the accompanyingdrawing. forming` part of this specilica'tion. and in 'which-f Figure l is a plan viewppartly in section, of a plionoaraph constructed in accordance with my invention` the parts being arranged for feeding;l the sound box carriage at a suitable speed for operating upon records havinf.T two hundred threads per inch; Fig'. 2 is a similar view. .showing the partel arranged illustrated in Fig'. 2. the geeL for feeding` the carriage at a suitable speed for operating;r upon records` having' one hundred threads per inch; Fre'. 3 1s a section ou line of Fie'. 1 Fier. 4 ie an end view of the feed screw shaft; and Fig. 5, is a fr e view of tlie;-:leeve which engages the end of the said shaft.

ln these views correspondingr partsvare represented by the .same numerals ofi-eference. Y

The phonograph shown is of a well-.known type, and comprises a base or body 1, upon which is rotatably mounted the main shaft 2, which carries 'at one end, the drive pulley 3, and at; the opposite end the mandrel 4, for supporting' the sound record. This shaft may be supported in any suitable manner, but I have shown the same journaled in a bearing a' intermediate its ends, and the end upon which the pulley is mounted is cupped,

11 of tine pitch, preferably one hundred threads to the inch, said screw shaft being,r iournaled at its inner end directly upon the 'l shaft 2, as shown, and its outer end upon a bearingl sleeve l2, interposed between the two shafts. The outer end of the screw shaft 10 is cutaway to form a pair of oppositely disposed tongues 13, and upon the shaft ,2 is slidably m'onnted a sleeve 14, having a pair of notches 15, which receive the tongues 13, of the shaft 10, thereby keying Said members together. Upon the sleeve 14e fixed a Spur gear 16. which is provided 'with one or more pins 1T projectin;r from 'its face and adapted to engage fixed upon the hub of the llhen in fr position, as

d 16 and 19 are looked 'together and the screw .shaft 10 is therefore locked to the drive pulley 3 and shaft Q, and rotatesat the same speed, and therefore feeds the sound box carriage 2O by reaSon of the engagement of the feed nut- 21 with the screw lr11 at. a rate Suitable for gear 19, whichis drive pulley 3.

operating upon records having, one hundred threads per inch.

Meshing with the gear 19, is a spur gear 21, which is journaled ona pin or stud 22, carried by a frame 23. This frame is sleeved at its-rear upon the by the set screw 25; the forward end of said frame is supported by the pin 9.

Upon the hub of the gear 21' is fixed a spur gear 26, which is adapted to mesh with the, gear 16, when the latter is 4in the position shown in Fig.r 1. Then the arts are in these positions', th hollow sha t 10 rotates upon the shaft'2, anl isdriven from the pulley 3 'through the gear train 19, 21, 26 and 16, which gears are so proportioned as to drive the shaft 10 at; half the speed of the shaft 2, and thereby feed the carriage 2O at 'a rate suitable for operating upon records back rod 24, and secured l the engagement of ythe pins lwwith the openings 18, as shown in Fig. 2, and in order' to adapt. the instrument to operate upon records having two hundred threads per inch, it is necessaryonl? 'to move the sleeve 14 from the position o Fig. 2 'into that of 'the rotating hollow feed screw shaft, of a rotary power' shaft within sald screw. shaft, means for locking said shafts together so asi F ig. l.

Having now I claim 1s:

described my invention, what 'Y 1. In a phonograph, the combination with to rotate' at the same speed andinterchang'eable means forfgearing .said shafts together sopas to rotate at 4different speeds, substantially as set forth.

- said gear` train,

2. In a phonograph, the combination with the rotaryliollow feed screw shaft, the traveling carriage and means co-.acting with the feed screw for progressingthe same, of a sound record support, a main shaftadapted to rotate said support and situatedwithin .the feed screw shaft,.means for drivingsaid main shaft, and interchangeable means for driving said feed screw shaft from said main support at vdifferent speeds, substantially as setforth. t

3. In a phono raph, the combination of `the main shaft a apted to'rotate the sound record support, a rotary hollow feed screw shaft surroundin said main shaft, a slidable sleeve rotata le with said screw shaft, a partial gear train coupling and gear means carried by said sleeve, .said sleeve being adapted thereby to interchangeably `couple said shafts togetherdirectly and vthrough whereby one shaft may' e drivenfrom the otheratv different rates of substantially as setf'forth. 4 Ina phonograph, thecolbination of a main shaft adaptedl to rotate *the sound-rec- ,.,ordsupporh a rotary-hollow feed screw' low Vshaft ations-halfthe speed of the.` main shaft, substantially as set forth. 6.,-In a phonograph, the combination of the main shaft adapted to rotatefthe sound record support, a rotary hol-low feed screw shaft surrounding said main shaft, a d rlve pulley secured to said main shaft, a spllned sleeve slidable upon said screw shaft, and means for couplingsaid sleeve and pulley together, substantially asset forth.
